Christ came to free us from sin's slavery as well as its penalty
Thesis III. But God took pity on the human race, lost through its own fault, and sent his Son Christ into the world. Christ was not only to free people from the punishments their sins had justly earned, but also to release them from slavery to sin.
He was to give them the grace by which they could once more serve God in true righteousness and holiness and make a start on a new obedience to his commandments.
Latin
III. Sed Deus generis humani, culpa sua perditi, misertus, in mundum misit Christum filium suum, qui non solum homines liberaret a poenis, quas peccatis suis juste commeriti erant: Verum etiam illos a servitute peccati eximeret, & eam conferret gratiam, per quam rursus possent Deo in vera justitia & sanctitate servire, novamque mandatis ejus inchoare obedientiam.
